Gassho-zukuri: japanese traditional building video

Great video of a Japanese building style with interesting shots of thatch roof replacement. Keep your eye out for the guy with the giant wooden needle. Anyone have a guess as to what's going on with the big hammers?

Iron rusts from disuse, stagnant water loses its purity, and in cold weather becomes frozen: even so does inaction sap the vigors of the mind.
